Greer doing it over again in ABC high-school sitcom

You may have your diploma, but do you ever really leave high school behind?

That's the idea behind the new ABC sitcom "Miss Guided." Or as Judy Greer puts it: "If you could do it all over again in high school, would you?"

Greer, 32, stars as Becky Freeley, who returns to her alma mater a few years later as a guidance counselor. Her character's return gives her a shot at "doing it better the second time around," she said.
